Note that 'lists' are really sequences according to the XDM model, but don't let that put you off.
These are lists of items [sequences ] which might be strings for instance. Created with the '(' ... ')' notation. For example
To access the command line parameters from a script, as, say 'xmlsh scriptname a.xml b.xml c.xml
parms=$*
() creates a sequence {} preserves one when calling a function, another script or even calling an initial script.

=====Plain sequences=====
===Using variables holding sequences===
The rule is
() creates a sequence {} preserves one
given a seq in $x
x=(a b c)
y=$x #y is now a list
To call a function with x as a parameter, use
functname param1 param2 {$x} is the required syntax
which ensures that the function receives, and can process $x as a sequence.
